The man, identified by police as 35-year-old Edgar Valdez, was apprehended by a local security guard, who placed the man in handcuffs until San Bernardino police arrived, according to Lt. Rich Lawhead.

Perez said the man chased her, threw her to the ground and tried to pry the stroller from her hands, but she refused to let go.

The stroller toppled over as well, but the baby strapped inside was not hurt, authorities said.
